Airtel — postpaid sim network issue

Address: A/205, Regency, Agarwal Township, Bhabola, vasai west, Thane, Maharashtra, 401202

Mine is Airtel post paid sim and Not getting 4G network from my residence. Most of the time network gets downgrated to 2G/3G. I am not able to access internet. Frequently I have to put on air flight mode and back to reset my network. I have been complaining to Customer Care for over last 6 months. Everytime I complaint, they inform there is new tower coming up in your location next month and this goes on.
